Collected by Patrick Wagstrom <patrick@wagstrom.net>

This is a Neo4j Database database containing most of the data surrounding the Ruby on Rails project on Github. The data were collected in May 2012. GitMiner project. More information about how to use the data is avaialble on the GitMiner project page.

understanding the data

The best way to get a grasp of the data is to read our paper from MSR 2013, "A Network of Rails: A Graph Dataset of Ruby on Rails and Associated Projects". It describes the data in more detail and provides a handful of [Gremlin][gremlin] queries that might be helpful for someone exploring the data.

After reading the paper you should take a look at overview.txt, which contains summary information regarding all of the vertices and edges in the dataset and covers how they're linked together. This is particularly useful if you want to know how to get from one vertex type to another.

Finally, our presentation from MSR 2013 is available online. Feel free to check it out.

It's just data, however it was produced under the auspices of a joint study agreement between IBM and the University of Nebraska-Lincoln, therefore the data are licensed are the terms of that agreement which requires that all output be licensed under the Apache License v2.0. I'm not certain what that means for data, but that's the rules.

If you're an academic and publish a paper using this data then a citation is highly appreciated (co-authorship is even more appreciated, I can help you make sense of the data). If you're looking for a citation use something like this:
